 Notable changes
 ===============
 
-### Mempool Policy
-
-- The maximum number of potentially executed legacy signature operations in a
-  single standard transaction is now limited to 2500. Signature operations in all
-  previous output scripts, in all input scripts, as well as all P2SH redeem
-  scripts (if there are any) are counted toward the limit. The new limit is
-  assumed to not affect any known typically formed standard transactions. The
-  change was done to prepare for a possible BIP54 deployment in the future.
-
-- #32521 policy: make pathological transactions packed with legacy sigops non-standard
-
-- The minimum block feerate (`-blockmintxfee`) has been changed to 1 satoshi per kvB. It can still be changed using the
-configuration option.
-
-- The default minimum relay feerate (`-minrelaytxfee`) and incremental relay feerate (`-incrementalrelayfee`) have been
-changed to 100 satoshis per kvB. They can still be changed using their respective configuration options, but it is
-recommended to change both together if you decide to do so.
-  - Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by
-  the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume.
-  - Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee
-  rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; `-mintxfee` must be changed
-  before attempting to create transactions with lower feerates using the wallet.
-
-- #33106 policy: lower the default blockmintxfee, incrementalrelayfee, minrelaytxfee
-
-### Logging
-
-Unconditional logging to disk is now rate limited by giving each source location
-a quota of 1MiB per hour. Unconditional logging is any logging with a log level
-higher than debug, that is `info`, `warning`, and `error`. All logs will be
-prefixed with `[*]` if there is at least one source location that is currently
-being suppressed. (#32604)
-
-When `-logsourcelocations` is enabled, the log output now contains the entire
-function signature instead of just the function name. (#32604)
-
-### RPC
-
-- The `dumptxoutset` RPC now requires a `type` parameter to be specified. To maintain pre
-  v29.0 behavior, use the `latest` parameter. Documenting this change was missed in the v29.0
-  release notes. (#30808)
-
-### Updated Settings
-
-- The `-maxmempool` and `-dbcache` startup parameters are now capped on
-  32-bit systems to 500MB and 1GiB respectively.
-
-- #32530 node: cap -maxmempool and -dbcache values for 32-bit
